Very comfortable but I do get hot sometimes

This has been an exception mattress where comfort is concerned but it tends to trap a lot of body heat. I often have to through the blanket off and sleep under the top sheet alone just to keep cool. Not sure that any brand of foam mattress would perform better although I hear all kinds of wild claims in the commercials. For now though, I like this mattress. In the summer sleeping under the sheet only is fine. In the winter when the room is cooler I'm a happy camper under the blanket / comforter.
